. Application filed October 31, 1908. Serial No. 460,400.

To all whom it may concern:

Be it known that we, Ann one of Basel, swltzerland, and HANS KUNY, of

which the following isa full, clear, and exact SPQC1fiCilt-10D Thisnivent on relates to a loon'r for weaving ribbon, particularlyvelvetisribbon 1n 1 which the driving mechanisms for the healds(harness) and for the shuttles are so arranged with reference to that ofthe lay that for each stroke of the lay the shed is twice opened and theweft laid in twice. In consequence of this arrangement it is possiblefor our ribbon loom to work more quickly and to furnish a greater lengthof ribbon in a given time than the ordinary ribbon loom.

In the accompanying drawings: Figure l is a partial front View and Fig.2 a side elevation of an embodiment of the invention.

The main shaft (4 of the loom is driven from the pulley device 6 bymeans of the toothed wheels 0, (Z. To operate the lay or batten 0 thereis an adjustable crank pin f on the wheel 0 which is mounted upon themain shaft 0, and this crank pinis connected by a connecting rod 9 withthe arm ii of the lay or batten c which is pivoted at i in such a way asto be compelled :to partake of its motion. Thus for each rotation of themain shaft 0 or of the wheel 0, the lay or batten c executes a toand-fro movement, that is to say a beating-up and a return stroke.

The jacquard of the loom for controlling the heddles or healds is adouble acting ma chine of the usual type with two blades, two sets ofwires and two jacquard rollers, so that its various parts need not berepresented and described in detail for the present purpose. It suflicesto state that the heddles or healds are attached to oscillating membersconnected tqtwo horizontal rows of hooked jacquard g wires alternatelythrough the medium of two series oflift-ing '-wires, "tlietwo jacquardrollers in such a wayj'that ea'ch time. that jacquard blade which movesforward draws with it the acquardwires which-have not heenlifted by thecorresponding lifting wires and thus HANDsonIN,

its motion, I and the toothed wheel en: gages with a toothed wheel qmounted eccentrically upon the pin 0 while a -spur wheel 1' connectedwith the toothed wheel' g engages with the wheel a mounted upon the 55'or at each working stroke of the battenor lay. Indeed, as will be-seenfronithe' draw .ing, the diameter of thewheel cis double that of wheel1', and the number of teeth'of revolution of the main shaft a of theloom,

r is half that of p, so that at each rotation .of

the main shaft 64 the elliptical toothed wheel 7) is turned once andconsequently each jacquard blade is. swung to and fro once and the shedthereby twice opened.

As will be seen from Fig. 1, the batten.

or lay c is a so-called double batten 2. e. a batten with two rows ofshuttles j-lying The shuttles j of each row are moved to and fro intheir paths in the known way by means of a toothed. rack 3 moving to andfro. The toothedracksc for the two rows of shuttles are connected .at-

t and 23 respectively, with a treadlee by means of two ties usecured tothem atthose points and shown by dotted lines, these ties being carriedupon rol-lers, both upon the,

connected at w and a: by two ties 3 (indt cated by full lines) securedto them at those points with a treadle a, these'ties being carried onrollers on the batten in a direction over rollers. These treadles o, eare articu lated to the framing of the loom at 1 and .106 opposite tothat/of the ties u, and above also- T 'rmidles v and 2 are eachalternately moved .up and down once by the cams 2 and 3,

tively one to another than when one treadle (2' for example in Fig. 2)is at its highest rotation of the main shaft a from which a I actingpositivel opened and closed upon each occasion, and

parted to them by the action of two cams 2, 3. The cams 2, 3 are mounteddirectly upon the main shaft a of the loom. They have a different shapeof so to speak com- 'alenientary form and are so arranged relapoint, theother treadle is held at its lowest position by its own cam, with theresult that the shuttles of both rows stand at one mar their stroke, andupon reversal of the' position of the treadlesare carried to the otherend of their stroke. Thus at each stroke 'of the batten or lay resultsthe which together with the treadles v and z, and the parts combinedwith them represent the drivin mechanism for the shuttles, 1 in everysense so that the shuttles of the two rows are simultaneously moved onceto and fro, so as to lay in two shotipn each occasion, the arrangementbeing so contrived that the motion of the shuttles in one directionfollows immediately upon one of the two openings of the shed broughtabout for each stroke of the battenby the jacquard driving mechanism,and the movin of the shuttles in the reverse direction immediately afterthe second opening of the shed.

The driving of the double action jacquard machine by means of theelliptical toothed wheel 1) has the advantage that the healds are soactuated that the shed is rapidly every time affords a proportionatelylong open condition of the shed, so that all contact of the shuttleswith the threads of the warp is prevented.
